I know that. However to make it worth the extra piping you have to run significant boost pressure, preferably at high rpm. The engine block may be smaller but the extra exhaust piping, intercooling, etc. will add weight back. A small 4 cylinder engine weighs barely over 200 pounds, so a 40-50 pound increase from a turbo kit is very significant.
